Application filed October 1 To all whom it may concern 1 Be it known that I, ORVILLE F. SHA'rrUcK, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new an useful Door Carrier; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

The object of this invention is to improve the construction and operation of means for mounting a door'for a structure, and a carrier for releasably engaging the door, detaching it, moving it laterally to another position and replacing it in closed position.

The invention is made with particular reference to lumber dry kilns and other structures, such as shops and garages, where a plurality ofdoors is required for a plurality of door openings, and it is necessary that each door may not only be opened but moved laterally out of the way of the door opening, or moved to another door opening. To that end a single track rail is secured to the structure above the plurality of door-openings, and a single carrier or frame is adapted to travel on sald track and pick up any door and move it away and replace it in doorclosing position.

One feature of the invention consists in improved means for suspending the door 1n closing position so it will hug tightly to the wall of the building, by securing to the top of the door a plurality of door hanger fixtures, preferably in loop form, each'adapted to engage an outward leg andupwardly inclined hanger hook on the track fixture, which is in the form of a plain arm of a width appreciably less than the width of the door hanger, so as to avoid any niceties and difficulties in closing the door and removing the same. Heretofore the .fixtures for accomplishing this work have been complicated and difficult to operate because they were close fittin and in fact required an accurate and wedging fit that made it difli cult to close a door and even to open it and required great care.

Another feature of the invention consists in providing a plurality of fixtures on, outside of, and near the top of the door, having a plain plate with an elongated notch or recess in its lower edge; and providing a cardby 7, 1925.. Serial No. 63,106. f

rier with a corresponding"plurality of lifting arms, each having a relatively thin projection or hook adaptedto engage the plate on the door in said elongated recess, wherethe carrier can with ease engage and pick it up very rapidly and quicklyfor transporting the same. Heretofore, the door lifting fixtures also have been so made asto require relatively 7 close fittingv and great pains in operating the same so as to cause said fixtures to properly cooperate.

VViththese and the otherimprovements herein set forth and claimed, the operation of such door carriers and the removal,*t ransportation and replacement of the doors, especially metal doors, is greatly facilitated. Much less. care and pains is required and, therefore, the operations can be made very rapidly and without any failures in the operations. Y I

The full nature of the invention will be understood from the accompanying draw-v ings and the following description and claims:

or like construction having a wall 10 with -aplurality of doors 11, three being shown in Fig. 1, for closing 'door openings located be tween uprights or door jambs 12. Railway track rails 13 are shown on the floor along which cars loaded with lumber or the like, not shown, are moved into and out of the dry Said doors are required to be individually opened and moved laterally out of the way of a. car as it is moved into or out of the kiln. This The structure preferably has along the top of the 'door openings a strong beam 15 extending horizontally and preferably in the form of a metal angle bar, as shown in Figs. There is also a horizontal track rail 16 secured to the building at a point just above the door openings, as shown in Fig. 1. This track rail has the general shape of a T-railway rail of ordinary type, but it is mounted in a horizontal instead of a vertical position, as shown in Fig. 6. This is done by a track fixture 17 that is secured to the dry kiln structure and preferably to the beam 15 by bolts 18, as shown in Fig. 4.

This fixture has an upper arm projecting 'outwardlywith a. track receiving clamping across the upper end and a rear upper member of the angle bar 27.

head 19 thereon adapted to receive the lower.

edge of the base of the track rail 16 and the upper edge of said track rail is held by a bracket jaw 20that is secured in place by a bolt 21 which extends through thebracket jaw and around a tubular portion 22 of the track fixture 17. There are preferably two of these track fixtures over each .door opening, but the track doors! Three doors are shown herein, but the number may be greater or less, as desired. The trackfixture has a hanger hook 23 at the lower end thereof, as

shown in Fig. 4, upwardly and outwardly inclmed, on which the door is supported in closed position, as shown in Figs. 1, 2 and 4. The door 11, in the form shown in Fig. 4, is a metal door having a front plate 25 an angle bar 27 at the upper right-hand corner. To the plate 25 or upper front part of the door there is secured a lift plate 28 by bolts 29. It has a rearwardly extending projecting plate 30 that extends under the The fixture 31 is secured to the top of the having a bottom through which a extends and secures it to the angle hanger door, it bolt 32 bar 27 and the horizontal plate 30, and said hanger fixture is secured to the upper end of the plate 28 by a bolt 33. The fixture 31 has a horizontal hanger bar 34 adapted to engage and be supported by the hanger hook :hung or held suspended and in rail 16 is continuous for. the whole series of plate 26 and.

23 of the track fixture 17. There are two of the hanger fixtures 31 on the door and they are supported by two of the hanger hooks 23 and in that manner the door is closing position, as seen in Figs. 1, 2 and 4.

The door is disengaged from the structure and opened and held open and supported on the track rail 16 by a carrier, as shown .in Figs. 1 and 2. This carrier has a frame formed substantially as shown in Fig. 1.

of parallel side bars arranged V-shaped at the lower end and rigid connecting rods 41 and 42 and top rods 43 and 44. There is also a vertical rod 45 at the lower end of the carriage frame extending from the horizontal rod 41 down to the lower This carriage frame is supported on the track rail 16 by brackets 46 and flanged rollers 47 which are mounted in said brackets. The bracketsare secured between the upper ends of the parallel side bars 40 of the carriage frame by means of the two rods 43 and 44. The lower end of the carriage frame is held in place with relation to the door by a link 48 on the frame and a hook 49 on the door, asshown in Fig. 2.

The door is picked up and supported by lifting arms 50 which are fulcrumed between the parallel side bars 40 of the carrier frame at 51, as seen in Fig. 2, and each lifting arm has at its upper end a finger 53 projecting rearwardly and adapted to be inserted under the lift plate 28 in a groove 54. A lever 55 is pivoted to the upper end of the lifting arm 50 at 56 and to the upper end of a triangular frame 57. This frame consists of three rods, the upper one horizontal and the two side rods extending outwardly and inwardly and slidably connected with the vertical rod 45. There is also a lever 60 pivoted to the upper endof said triangular frame at 61 and to the parallel side bars at 62 slightly above the pivotal point 51 of the lifting arm 50. Vith this construction, when the triangular frame 57 is forced downward from the position shown in Figs. 1 and 2, you can lift the door off the hanger hooks 23 upwardly and outwardly to the dotted line position shown in Fig. 2. he downward movement or operation of said triangular frame is effected by a hand lever 65 which is'pivoted at one end at 66 to the lower part of the carrier frame and between the ends of said lever 65, it is connected bythe connecting bars 67 with the lower end of the triangular frame 57. The downward movement of the hand lever 65 will cause a downward moveient of the triangular frame 57 to bring it into the dotted line position shown in Fig. 2, and that will lift the door off itssupporls, and then the door will be supported by the carrier on the track rail 16, and the door can then be moved laterally on said track rail to either side as far as desired.

apex of the frame.

- fixture 17.

VVhe-n it is desired to close the door, it is caused to travel on said track rail laterally to a position'in front of the door opening and then the hand lever 65 is moved vertically so as to cause an operation of theme nbers of the carr age opposite to that during the opening movementof the door, whichcauses the door to be moved inward toward K the structure,

downwardly and inwardly inclined surface 72, so that the weight of the door acting through the pins and the inclined notched surface 7 2 will cause the middle part of the door to wedge downwardly and inwardly toa tight closing position.

There is a general door support having no relation to the carrier heretofore described, to be seen in Figs. 1 between the rail fixtures the rail 16 bya clamp 7 6 and is secured to the frame beam hanger hook 23 similar to that on the-track A hanger fixture 7 8 is: secured to the top of the door by bolts 79 and it has a horizontal hanger bar 80 which is adapted to move in over and slide down on the hanger hook 23 when the door is moved to closing position, the same as happens with reference to'the hanger bars 34, and the hanger hooks 23 in the structure heretofore described.

It is to be noted that the hanger hooks 23 are single arms projecting upwardly and outwardly from the fixed part of the structure and are relatively narrow, while the hanger bars 34; and 80 are very Wide, several times the width of the hooks 23. Likewise the recess 54 in the lower edge of the lift plate 29, see Fig. 3, is very wide, while the upper end of the lifting arm 50 is relatively very narrow, as compared with the width of the recess 54: in the plate 29. Likewise there is a long recess 81 in the upper end of the lifting arm 50. These and the otherfeatures of the construction are such as to enable the door to be readily picked up and moved to an open' position, and likewise return to closing position without any niceties of operation and without taking any particular pains and care, such as has been required by similar apparatus heretofore: With a number of doors in line and rapid action required for opening and constructions or warplng or any The plate 71 at the bottom of the notch therein has a and 5. It is midway 17 and it consists of a vertical fixture 7 5 that is clamped'on l5 bybolts 77 and has a closing and mov ing them, itaifords a great saving of time and expense'for the door construction to be. such that when the parts are moved into approximately proper positions, they will engage each other and operate satisfactorily. Thus the fingers of the lifting arm 50 do not have to belocated in any particular place in the slot 54- under the plate 29, nor does the hanger bar 3%! require. to be located in any particular place on the hanger hook 23. This enables rapid and satisfactory operation of such apparatus to be accomlished. It also enables the apparatus to satisfactorily operate regardless of defective other slight irregularity in the-form or arrangement of any of the parts of the apparatus. This is particularly important in metal doors which expand materially and warp under the influence of the heat and coldand of wooden doors which are affected materially by moisture and dryness.

' Fig. 6 shows a modified form of the upper end of the door where the lift plate 28 and bar 30, hanger fixtures 31 and hanger bar 84, are allintegral. I

A modified arrangement is shown in Figs. 7 and 8, relative to wooden doors on lift plates 28 being provided with a horizontally rearwardly extending plate 30, and there is a hanger strap which at itsupper end is securedto the hanger fixture 31 andplate 28 by a bolt and nut 86. The rear, end of the hanger strap 85 is bifurcated, as seen in Fig. 8, and the twolegs thereof are secured to the rear part of the door by the-bolts 29. This makes a very strong construction for mounting said fixtures on the woodendoors;

The hanger hooks 23 are preferably inte-' gral with thetrack fixtures 17, as shown, in; order thatthe relation between the hook 23 and the railf16 may be at all times maintained. While the hook 23 may be separate fromthe track fixture 17,.that would render it more difficult to maintain the exact relationship between the hook23 and the track rail 16. Unless this relationship be maintained, the hanger bars 34iat the top of the doors would not'always register with the books 23 in closing the door. Also in this device there is a fixed relation between recess 54 in the bottom of the lift plates 28 and the track -16and hanger hooks .23, so that the carrier can always replace and remove the hanger bars 3d on and from the hanger hooks 23. This fixed relation is due to plates being fastened to the hanger bars 34.
